A runtime memory allocation tracer, like a hot spot analyzer for memory allocation, can help analyze overall memory usage, peak memory usage, kernel module memory usage, all combined with stacktrace. Userspace memory trace is planned and not yet implemented.
This tool works by tracing all page-level memory allocation events in kernel (currently supports using perf or ftrace), and actively integrate the events into a stack trace tree. It can also work with kernel's page owner log file and use as a memory usage viewer.
I tested this tool today and it is quite useful for development and monitoring the operating system, it seems to work very well, you can even see in the screenshot how ...
You can find this project on the GitHub repo.
